Chapter 1

The transmitter must be relatively close-coupled to the probe in order to achieve this improved

performance. This is achieved by direct connection to the probe through short probe-connecting

adapter, or in the case of some retractable probes through a cable of no more than 2 meters (6

feet) length.

A typical installation of a Corrater transmitter is on a high pressure access fitting with a flexible

conduit connection cable. The transmitter and the connectors that attach to it are explosion-proof

(flame-proof).

Warning: Power must be removed before disconnecting either connector on the

transmitter if explosive gases are present

The Corrater transmitter may be used for continuous on-line monitoring systems with or without

Microcor transmitters. The 24 VDC power supply and the RS 485 communications in an online

system allow multi-drop connections between the central corrosion monitoring computer and all

of the transmitters, which minimizes cabling costs. Each transmitter has internal DIP switches to

set the Identification Number or Address of the transmitter from 0 to 31 for communications

over the two-wire RS 485 bus.
